Where is the radiator of the refrigerator? How does the radiator of the refrigerator work?

First, the working principle of the refrigerator radiator: any substance should release heat after liquefaction and absorb heat when gasification, which is the most common physical phenomenon. Air-conditioned refrigerators use this principle to liquefy the refrigerant to release heat, and then let it evaporate to absorb heat. The location of heat released by liquefaction and the location of heat absorbed by evaporation cannot be in the same place, otherwise it will have no effect. Therefore, the air conditioner has an outdoor unit for heat dissipation and other main functions, while the refrigerator has a radiator outside the refrigerator, which is made of iron pipes. As long as all electrical products are radioactive and the refrigerator is radioactive, we should try to avoid opening the refrigerator when it is working. In addition, there is too much dust in the radiator pipe of the refrigerator, and the electromagnetic radiation is greater. It is an effective way to reduce electromagnetic radiation to use vacuum cleaner to suck away the dust on the radiator pipeline and improve efficiency. If it is convenient, it should be put in the kitchen. Both sides and door frames are exposed. When the refrigerator works, the radiator is slightly hot.
